I'm after a bit of advice with regards to a new boiler sytem and fire. I am looking to fit a tunnel fireplace between the front room and dining room so it appears on both aspects. The problem is that currently there is a back boiler where this fireplace would go! Now the questions is what type of boiler to replace with? and where? Also will a fireplace of this type produce any heat or will it just become a focal point (albeit an expensive one!!!). The house is a three bedroom, semi with one main bathroom and downstairs wc and has 10 rads. Many thanks lewy

Would be best to install a condensing combination boiler. If there's a cupboard with a tank or cylinder in the Combi could go there. As long as the condensate pipe can be ran to discharge somewhere suitable.

Or on a outside wall, for example in the kitchen, it all depends on the accessibility with pipes and gas supply.

There's many places a combi boiler could be installed.

As for the fire, is this going to be gas ? or coal/wood burning fire ?

The gas fire would probably be more of a dedcorative feature rather than a form of heating. Whereas a real fire would give off more heat, but would have to check with local authority you're not in a smokeless zone.
